Application filed April 8, 1910. Serial No. 554,099.

To all whom it may concern: Be it known that I, HENRY B. CooLnY, a citizen of the United States, and a resident of New Britain, in the county ofHartford. and State of Connecticut, have invented a new and Improved Tubing-Machine, of

' which the following is aspecific ation.

My invention relates to the class of'ma-.

chines more especially designedfor folding. paper or the like into various shapes and,

for securing its edges or other parts to produce tubes andsimilar devices, and the ob" ject of the invention ,is generally to providea machine of this .class having numerousj novel features of advantage and .utility.

'A machine embodying the invention in one of its forms is shown in the accompany-f ing drawings, in whichv Figure 1 is a plan view of a portion of a tubing machine embodying .myinvention,= with parts in therelative positions assumed just at the time a sheet has reached its place. to be folded. Fig. 2 is a view in cross-sec- Ition. through the machine on. a plane denoted by the dotted line 2 2 of Fig.1, parts be yondbeingcinitted. Fig. 3 is a detail view" in lengthwise section through the'niachine'i on a plane denoted by the dotted line jof Fig. 2. Fig. at is a diagrammatic viewillustrating the adjustable feature of the; feed wheels, one wheel being shown as hav-- mg. just reached a position to engage a sheet. Fig. 5'is' a like view, but showing the other wheel as just leaving the sheet. Fig. .6 35

is a detail view showing the construct-ion of the gummer cylinder, a part of which is. shown developed .on a fiat plane. Fig. 7 a detail end view of the gummer cylinder.- Figs. Sand 9 are detail views illustrating? the construction of the guminers.

In the accompanying drawings the nuineral 10, denotes the frame of the machine composed of any suitable material and of; any desired shape, in the emb'odimenthere in shown this including members forming the sides of the machine and suitably spaced;

apartito receive the mechanism therebew n, hich sides maybe joined and rig idly secured together by any suitable means' Thesesides areinformedc to receive boxes or bearings for shafts, feed rolls, etc. which aredriven in any suitablemanner, in the'con adriving pulley 12 to receive a belt, by

means of which the machine may be driven.

My improvement relates especially to the mechanism for folding and for gumining the sheets and the feed devices therefor, and for this reason, only so much of the machine as embodies such mechanism is shown herein. This mechanism includes rolls, usually arranged in pairs for causing the sheet to travel through the machine, these rolls in some instances performing other functions.

A pair of feedrolls .13'1 tare suit-ably mounted in the side parts ofithe frame, the upper roll being driven as by means of a pinion 15 meshing with a gear 16"secured to the lower roll, the latter being driven through a train of intermeshinggears, hereinb'efore. mentioned, extending to the mainshaft 11, said gears. beingsuitably disposed and arranged to cause rotation of the several parts in proper direct-ions and to feed the sheets at the required speed.

A gunimer 17 in the .form of a cylinder is mounted on a gummer shaft 18 supported in-the side parts 10, a roll 19-to cooperate and in contact withthe gummer being. mounted in the-side parts of 'the frame. pinion on this rollnieshes with a guminer gear 19' onthe gummer shaft, said gear meshing with. an intermediate gear 20 between it and the feed 'roll'14, saidfinterme diatc gear meshingwitha pinion 20 on said feed roll shaft for the purpose of d'riving it. Thegear 19 is driven from the shaftll by means of an intermediate gear21.

Aformer bar 22.is preferably-removably mounted in the side. parts ofthe frame, in the construction herein shown this bar being held between the ends of'barsupp orting.

studs or screws 23 mounted'in the side parts A and having theirinner ends tapered to fit recesses in the opposite ends of the bar; Tllis bar has a. permissive turning movement on the studs 23, a stop arm 24'beai-ing astop plate'25beingsecuredto thehar, said plate overlying the frame of the machine and having if desired a stop screw 26 by means of which the position of the bar may be adj ustably determined.

A former bar spring 27 secured at one end to a former bar spring arm 28 and at the other end to a folding blade spring arm 29 extending from the side of the frame holds the stop screw 26 against the side part of the frame. A former 30 is secured to the former bar 22 in any suitable manner, as herein shown a former base 31 being adjustably secured to the bar and the former beingremovably secured to the base, whereby formers of different size and shape may be readily employed. This former is of a shape to determine the shape of the article to be folded in the machine, the former herein shown being tapered as seen in Fig.

1 of the .drawings. 7

A supporting plate 32 is located directly beneath the former, in position to provide sufiicient space for the sheet and to permit its free movement into and out of said space. This supporting plate is secured to a cross-bar 33 extending across the frame and secured to the side parts thereof. This plate is preferably of such shape and size that the gummed edge of the sheet will overhang and lie beyond the edge of the plate. A holder sleeve 34 is loosely mounted on the bar 22 and supports a holder 35 adjustably secured to a holder block 36 fast to the bar. This holder is so located that its free end may engage, through a holder slot 37 in the former 30, with a-sheet passing along the space between theformer 30 and supporting plate 32 to temporarily retain the sheet against movement while it is being operate upon by the folding mechanism. The meeting ed es of the blank may be notched to provi e space within which the holder will be located when the edges of the sheet are folded together and thus prevent its interfering with the folding o eration. A holder cam arm 38 secured to t e sleeve 34 projects into positionoto be operated by the holder cam 39, the end of the arm being suitably equipped for such cam operation. This cam is secured to the gummer shaft 18 and is suitabl formed and timed to raise the holder su ciently to permit passage of the sheet and then to press the sheet against the plate 32 and hold it as above described. One end of a holder spring 40 is suitably connected with the arm 38 to retain it in contact with. said cam, the opposite end of the spring being secured to one of the folding blade spring arms 29, of which there are two, one secured to each side part of the frame.

having guide flanges 44 located in undercut portions 45 forming part of the openings 41. Studs 46 are secured to each of the guides, these studs bearing rollers engaging folding blade cams 47 secured to the shaft 11. A folding blade base 48 is pivotally secured to each of the slides 43 and a folding blade 49 is secured to each of the bases 48, The working edges of these folding blades are arranged to coiiperate with the former 30 to fold a sheet over its edges as the blades are forced toward each ether, in the preferred manner of operating and as herein shown the folding starting at the heel or rear part of the blade and working gradually toward the front along the edge, although to all appearance in operation the entire movement is practically instantaneous. The pivot of each of the blades bears a post 50 adapted to contact with a strike 51 adjustably secured to the frame of the machine, these posts, when the slides 43 are in their rearmost positions, or farthest apart, holding the blades ,in their lowermost positions. Folding bladesprings 52 are secured one to each blade, the upper ends of these springs beingsecured to the foldin blade spring arms 29. These springs hold t e blades in their upward (positions and against stop screws 53 a justably mounted in the stop arms 54. Springs 55 suitably secured at their ends to studs on the slides 43 draw theslides towardeach other and the cams 47 force the slides apart against the tension of said springs.

A feed shaft 56 is suitably mounted in the side parts of the frame immediately over the shaft 11 and this feed shaft bears feed wheels 5758 cooperating with a feed wheel 59 on the shaft 11. The feed wheel 59 is round; having its entire edge projecting through an opening in the cross-bar 33. In the preferred form of construction-and as shown herein this wheel 59 has two edges formed by a groove 50, each edge cooperating with one of the feed wheels 57 or 58.

The feed wheels 57-58 are cut away for a portion of their peripheries, this cutaway portion being of suflicient extent to allow movement of the folding blades to fold the sheet over the former 30. The'circularly formed edges of the wheels -57-58 pass ,through openings 6162 in the former and so that the edge of its circularly formed peripheral portion will be in position to engage the'periphery of the wheel 59 at the proper time to start outward movement of a sheet from within the space between the mascara former and the supporting plate, the'other wheel as 58 taking hold of the sheet an instant later. This other wheel as 58, however, is adjusted in the opposite direction on the shaft so that its peripheral edge will retreat from the'wheel 59 to stop feed of a sheet at the proper, time into said space, thewheel 57 releasing its hold an instant earlier. seen that one of the wheels is adjusted to start out-ward movement of a sheet from within the space at the proper time and the other to stop inward movement of a sheet into said space at the proper time, both wheelsthen releasing their grip upon the sheet after it has been folded, it being understood that the sheet entering the space between the former and supporting plate closely follows the sheet leaving said space, the feed wheels in a single rotation moving a sheet out of said space and a succeeding sheet into the space, the latter in position to be folded. Rolls (iii-64 take the sheets from the feed wheels 51-58 and 59 and A stop bar 65 is mounted at each end- 5 upon slides 66 supported for vertical movement in theside parts of the frame, these slides being connected as by links 67 with levers 68 properly equipped for reciprocation by cams 69. Springs 70 secured at one end to a stationary part of the machine and at the other end to the levers 68 hold the latter with their rolls in contact with the cams 69. The cams are so shaped that the stop bar 65 is moved opposite the space between the former 30 and supporting plate 32' at such times as the front edge of sheets approach this point; so that the sheets will be forced against the edge of the bar that forms a stop to properly'position the sheets for folding. When the folding blades have folded a sheet and while still incontact therewith the bar is raised justsufiiciently to allow said sheet to pass underneath it, the upper surface of the sheet sliding against .the blades and" bar that thus prevent the gummed edges from separating.

A portion only of the gummer or gummer cylinder is shown herein, this being suflicient for an understandingof its construction, which construction readily adapts the cylinder for work upon sheets having their edges disposed at various angles with respect to each other oreven parallel one with another. This cylinder 17 has lengthwise extending grooves 75 forming narrow ribs between said grooves. Gummers 76' secured within .said grooves project slightly beyond the surface of the cylinder in position to receive the gum from an suitable so'urcel Each gummer has a base 77 adjustable lengthwise in a groove, a screw 78pm jectingthrough aslot in the-base servingto From this construction it will be adj-ustablysecure the glimmer in position. It will be understood t atvthe gummers are arranged to apply the gum or adhesive along the proper part of the blank being formed.

The gum box for supplying the gummers is not described herein. as any well-known form'- of gum box known-to those skilled in the art may be employed.

In the operartion of the device, a sheet is delivered from the rolls 13-14 to the gummer 17 and its cooperating feed roll that grasp the sheet and carry it toward the folding devices. As the gummer rotates the gummers 76 come in contact with one edge of thesheet applying gum to the under side thereof. The gummer and its cooperating roll project the sheet into the space between the former 30 and sup )orting plate 32, the holder 35 at this time eing raised.

The parts having been moved to assume the relative positions shown in Figs. 1, 2, and 3, a sheet will have been placed in proper position for folding, at which time it pauses momentarily in its travel through the machine. At this time the bar 65 is in position where it stopped advance of the sheet, and the holder 35 has been just enaged with the sheet to hold it durin the folding operation, and the folding blades 49 are just ready to begin their forward or folding movement.- It will be understood that all of the cams for operating these several parts are properly shaped and timed to'efiect the required movement of a part at the proper time. The cams for operating the foldin blades are so shaped and formed thatone b iade completes its inward or folding movement just prior to the other, so that one edge of the sheet will be folded on top of the other edge, and the gummed surfaces thus brought together. These blades are now carried forward by the slides 43, the posts 50 retreating from the strikes 51, allowing the blades to be raised under the pull of the springs 52 until arrested by the stop screws 53. In the further movement of the slides the blades fold the edges of the sheet over the former 30, the cutaway portion of the feed wheels 5758 permitting this operation. The blades remain in this position during a part of the succeeding movement of the sheet and for the purpose of holding the gummed edges of the blank together until acted upon by other parts of the machine serving the same purpose.

Just after the blades have brought the two edges of the sheet together the advance edge of the feed wheel 57 encounters the sheet and thereafter the Wheel 58 encounters said sheet. The sheet is by this action of the feed wheels moved from the former-underneath the bar 65 which has been raised to allow passageof'the sheet- Closely following th'e'folded sheet a succeeding sheet is moved by the rolls and gummers hereinabove described into the place occupied by the folded sheet and closel following it. The advance part of the rol s 5758 move the folded sheet out of the space and the rear part of said wheels engage the unfolded sheet and move it into position, so that as the folded sheet is moved out an unfolded sheet immediately followsit and takes its place, the rolls 63-64 continuing the movement of the folded sheet. The bar 65 is brought down into position just before the front end of the unfolded sheet reaches this point and thus stops the advance of the unfolded sheet. As the folded sheet passes out the bar 65, being raised just sufficiently to allow this movement, by contact with the sheet, presses the folded edges together and holds them in this position until they are received between the rolls 63 and 64.

As the unfolded sheet reaches its position the holder 35 is actuated to press against the sheet and hold it while being folded. The blades 49 will be drawn back during the latter part of the movement of the folded sheet from the folder. As the blades are drawn back the posts 50 encounter the strikes 51, which action lowers the blades so that the incoming or unfolded sheet passes over the top of the blades, when the operation above described will be repeated.

Should the sheet become jammed between the former and supporting plate, the spring 27 will allow the former to rise sufficiently to avoid injury by reason of such jamming or wedging action, and by unscrewing one of the studs 23 the bar 22 and former may be readily taken out of the machine and the obstruction removed.

The roll 64 is driven by means of an intermediate gear 79 meshing with the main ear 80 on the shaft 11, said gear 79 meshmg with the gear 82 on the shaft of the roll 64-, the latter gear meshing with the pinion 83 on the shaft of the roll 63. The feed shaft 56 is driven by means of a feed gear 81 meshing with the main gear 80.

The construction is such that extreme rapidity in the operation of the machine is secured. The sheet itself is stationary during the folding operation, it simply pausing in its movement to permit the folding to take place, which operation is performed almost instantaneously, this pause in the operation of the machine being scarcely perceptible. The entire movement of the sheet,

is obtained by means of rolls so that the rapidity of operation is of the highest order.
